[Matlisp-devel] SIGSEGV Under CMUCL-18C and Matlisp

[Michael A. K. S. <mic...@ea...>]

Does someone have some insight to the following problem and how I should proceed to remedy the problem?

1.  I have two seperate RH Linux boxes; one with RH 7.x and one with RH 6.x.
2.  I'm running CMUCL-18C (glib2.1) on both.  
3.  I have built MATLISP (several versions routinely updated from CVS) on        both of these RH boxes w/o incident.
4.  I create an arbitrary complex matrix; call it CM.

Under RH 6.X the commands (IMAG CM) and (FFT CM) result in the following SAP related error:

> Error in function UNIX::SIGSEGV-HANDLER:  Segmentation Violation at    > >#x402F13D4.

> Restarts:
>   0: [ABORT] Return to Top-Level.

> Debug  (type H for help)
> 
> (UNIX::SIGSEGV-HANDLER #<unused-arg>
>                        #<unused-arg>
>                        #.(SYSTEM:INT-SAP #x3FFFEAF0))

Under RH 7.x the commands the commands behave as expected...i.e., they produce the right answer and no error.

Since this performance is consistant for various MATLISP builds, I tend to suspect either CMUCL-18C-glib2.1 or the glib-2.1.3 libraries...not MATLISP.  Any specific help/ideas out there?

tnx in advance
